If you’re planning on the International Builders’ Show in Las Vegas, expect to see not one but two modular homes built by Greenfab, the builder behind this modular, LEED Platinum home. The first home is a modified version of Greenfab’s 2100 Series home with 2,100 square feet, up to four bedrooms, and a master suite that opens to a large roof deck.

This is a prototype prefab — Paradigm — recently on display at Greenbuild 2012 in San Francisco, California. The modular home was designed by Bogue Trondowski Architects and built by Seattle-based Method Homes. The stunning little home of just under 700 square feet is eligible for 5 of 6 petals of Living Building Challenge and will also be certified LEED Platinum, according to Method Homes.

Santa Monica-based LivingHomes just announced the launch of three new designs — the CK4, CK5, and CK7 — based on the affordable C6 (also featured here), which made headline news earlier this year. CK Series designs are available for the price of $145 per square foot, not including installation or foundation, which is quite reasonable considering what’s available: a LEED Platinum level environmental program, high-quality modular build, and modern design inspired by Ray Kappe, FAIA.

This is Avant Garage, a four-unit residential project by Postgreen Homes in Fishtown Proper. Designed by Interface Studio Architects, these homes are targeting LEED Platinum and Postgreen’s President Chad Ludeman tells me he can see no reason why they won’t achieve that level of certification (just like the 100k House which also took home the USGBC’s 2010 LEED-H Project of the Year). Here’s a little background on this stunning new development in Philadelphia:

I’ve seen several projects pursue both LEED Platinum and Passive House certification, but I can’t think of any that actually went through with the aim other than this Passive House, Platinum-certified home in Taos, New Mexico. The 2,400 square-foot home has three bedrooms, two bathrooms, a garage, and 1.1 acres of land with a serene, scenic view of Taos Mountain to the east, Truchas Peaks to the South, and pasture land to the west.

Following the sale of Beachaus I, a contemporary prefab in the White Rock area of British Columbia, the neighboring Beachaus II now hits the market with a price tag of $1,275,000. The LEED Platinum home — three bedrooms, two-and-a-half bathrooms, 2,025 square feet — was designed by Pb Elemental, fabricated by Method Homes, and developed by InHaus Development.
